Catch-22 is a one-button, high-score game about the paradox of avoiding you problems, but creating other problems instead.
The goal of the game is to pick up the white orbs with the active player, and to avoid the inactive player (who is your ghost).
If you collect all three you switch to the ghost and your previous self becomes the ghost, repeating the actions you did before
the switch. This process is infinite untill you bump into yourself.
